To all who/m, 'it may concern:

Be it known that I, JOHN M. BROWNING, a States, residing at of-Weber andState certain new and useof which the Ogden in the county of Uta haveinvented ful Improvements in Firearms, following is a specification.

This invention while applicable to differ.-

ent kinds of firearms 1s more particularly-inblock;

5 .is a to plan view, and F1 6 1s a si e elevation of a pusher 1throughout the several views. The frame or receiver of noted by 2anditis generally speaking, like that shown in fore mentioned. I hemagazine comprises a passage 5, `into which the cartridges are insertedand fed automatically therealong. by the'flexible follower Gthe forwardend of which engages the rearmost cartridge to advance the line ofcartridges along the pasgreased cartridges.

I provide improved extracting means including. an extractor, actingtogether with the firing pin to', grip the rim of the car tridge whileit is being extracted, which does awaywiththe necessity of the lowerportion of the cartridge-'guide holding it to the ex tractor. Thecartridge being gripped between the extractor and the iiring pin isheld' securely while being extracted and until the in contact withthe'downward depending ejecting shoulder on the cartridge guide, when itis turned on the point of t e extractor andejected from the receiver.

Another object of my invention is to provide an adjustable extractor.When using cartridgesas s mall as the caliber A22 'and greased, therecoil spring cannot be very strong and the 'grease especlally in coldweather, has a tendency to gum up the ex. tractor and causeit to workslowly or not' at all, unless .it is provided with a fairly strong sprinhen a strong spring is used, if the hook on the extractor extends upwardtoo fai-, it has to be forced down by the recoil spring and if chamberofthe arrel. In the frame or receiver 2, is the breech-block 7, thebackward motionv of the breech-block being brought 'during firing, whilethereof is effected by the recoil spring (not shown). Thefiring pin isand its spring b 12,- the firing pin having a point 13, whic strikes thecartridge. v

After the foremost cartridge passes from the passage 5, it engagesthecam surfaces 8 and 9 and, asitffalls, i directed thereby into the vpath'of the breech-block7 which then. inserts ity into thec'hamber of thebar- Irel. This is the normal action, butthere may be cases, however, asI have already the block rebounds or is drawn back slightly for anypurpose, the recoil spring 1sy not strong enough to force the extractordown and the had Slightly the end of the barrel which I have a into theypath of the breechook. To insure vide means of a positive away fromcauses r'nisfring.A To prevent thls,

azine passa e is l into the pa of t e breech-block.l f,

As shown thismeans is 1n high enough to` en age the rim of -thecartridge properly 'an have no tendency whatever to hold thebreech-block away from thev endof .the barrel. I l

Referring to the drawlngis: L l Figure 1 is a sectional s1 e elevationof the frame, action and certain ladJunctiv'e mem-l bers of a rifleinvolving the invention, the

advanced. Fig. 2 is a practically similar view of the nel to receive theengages the bottom sion 17 which lits a ,cut Ain the'side of thebreech-block and thus prevents. endwise giga is a top plan. viewv of thebreech# i thev gun, is .de--

istv Y Li e characters refer to -vlike parts l.

the Letters Patent hereinbenoted, in which the cartrid e does not get Ithis latter result under all conditions, I proz nature by which theforemost cartrid e when out of the ma" us ed forward positive y?.

the form ofa pusher 113. oscillatoryon the upper side of thebreech-block, which'has a longitudinal chan- I pusher, the latter havingf about its central underside ythe lug 16 which Y of the channel. Inaddi-` v tion to this the pusher h as a lateral extenupward positionalso holds shown as tapered or pointed as at 18 which is adapted toenter an opening 19 in the lug 19 of the trigger plate, lthe uppersurface of the tail part ofthepusher having a cam surface 2O to causethe .upward tip of the forward end of the pusher when the tail thereof'enters the openingfl9.

It will be assumed that the breech-block 7 is moved backwardby recoiland that its forward end is back of the head of the front cartridge ofthe row, said front cartridge having just omer ed from the passage 5. InFig. 2 the breec -block is shown as all the way back, the pusherhavingbeen caused to be moved to its operative position. When,therefore,.the breechbl`0ck is advanced, the pusher will strike the headof the first ca rtridge, then out of the passage 5, and will positivelycause said first, cartridge to be guided downward by the cam surfaces 8and 9 into the path of the breech-block.

The extractor is denoted 'by 22 and it has a lug 23 loosely fitting acut 24 in -the front end of the breech-block. The extractor 22is-supported by the front end of the plun ger 25 loosely fitting asocket in the breechblock and engaged by the spring 26 to hold the frontcam end of the plunger against the lower cam surface ofthe extractor. Anexamination of the drawings, will 'show clearly that this thrust of theplunger 25 against the cam surface of the extractor 22,

while holding the extractor yieldingly in its the upper end of theextractor yieldingly against `the face of the breech-block. When thebreechblock is in its advanced position theA upper end of the extractorengages the rim of the cartridge in the usual manner. When the point 13of the firing pin strikes the cartridge the roughened end of the pointwill be slightly embedded and the yextractor will with the point clampjointly the shell to insurethe shell being withdrawn from place. As thebreech-block moves backward during which time the cartridge isgripped/by theextractor and the ring pin, it comes in contact with thedownward depending shoulder 27 at which time it is turned on the pointof the extractor and discharged positively from the receiver.

Through the breech-block 7 is tapped the screw 28 the upper end of whichengages the plunger 25 so that when necessary the extractor may beadjusted vertically throuoh the action of the screw engaging theptlunger and effecting correspondingmovements of the extractor.
